Delta Risk Cyber Threat Hunting is a professional security service that proactively searches client networks for undiscovered threats, including attackers that have evaded existing security controls. The service follows a structured five-phase methodology: 1. Prepare – Scoping and environment setup 2. Deploy – Sensor installation on in-scope systems 3. Collect – Data gathering and coverage gap resolution 4. Analyze – IOC investigation, false positive elimination, and customer collaboration 5. Report – Documentation of findings and recommendations Each engagement includes an initial scoping call, an on-site analyst team, 45 days of endpoint monitoring, and a final findings report with remediation recommendations. Analysts are trained in offensive and stealth techniques and investigate indicators of active intrusions, unauthorized activity, backdoors, and malware. Data is gathered from host and network artifacts across Windows, macOS, and Linux systems, including sensor logs and network device data. The service is designed to reduce attacker dwell time, validate network integrity, and identify threats that automated controls have not detected.
